not quite sure why the sprite ended up so tiny. skill issue on my end?

it's difficult capturing his resting bitch face in a constrained pixel sprite, the dimensions pose a fairly complex challenge. now he looks more plain than intended.. there's hope in alternative colors, but some more dabbling in sprite art variation or the life the animation takes down the line in the player characters development could bring some solace to this issue. for the time being however, this is the form our Odin takes, any suggestions? i wouldn't be against some opinions on the stylization before things are set in stone

also here are some doodles on paper of him just for fun, referencing his silly sprite self
